I still have guys calling me with this issue in the winter months here. Odd, but some are still having issues. I've sent out some revised tuning and made sure that they understood that things may change when it warms up so we'd readjust then. Only time (and hot weather) will tell.

The big fan fuel cooler idea may help, but you can't get below ambient in the tank and I think on a hot summer day she'll just heat right back up again as the temps are coming from the journey across teh valley to the CP3, the pressurization within the CP3 and probably to an even greater extent from the release/backflow at the injector.
